摘要：

A detailed collisional radiative model of W27+ ions was constructed based on the atomic data calculated by relativistic atomic properties software Flexible Atomic Code. The strong electric dipole (E1) transitions mainly comes from the 4 f → 4d transition in W27+ ions with wavelength falls into VUV region (4.6 - 5.1 nm), while the wavelength of magnetic dipole (M1) transition among the fine structures of the first excited states falls into the visible optical region. Synthetic spectra in both regions are given theoretically with plasma condition in EBIT for experiment reference. Finally, the dependence of the intensity ratio on the electron density is provided as a potential diagnostic tool of Maxwellian plasmas. © 2012 The Japan Society of Plasma Science and Nuclear Fusion Research.
